USB EZ-PD™ Type-C Forum Discussions

Hi, I'm looking into using the CY4533 as a power barrel replacement and also use it's internal USB transceiver. Unfortunately there is no information in the datasheet about the use of the USB C Transceiver part. THe CY4533 kit has just a power component and no USB connections. The connections D- and D+ have a comment "leave unconnected".

Where can I find some more information about the Transceiver part of the CY4533?

Thanks, Paul

Hi!

I know that PPS (source) is available in the SDK/lib for CYPD317x, but which other SKUs? We use CYPD4226 and CYPD312x and there is no support as far as we can see. We need to add PPS source to our dual-port dock design. Are there any dual-port SKU that supports PPS source on both ports?

Cheers

Hello

The CCG3 data sheet has the following description on page 5.
>Integrated Billboard Device

>CCG3 integrates a complete full speed USB 2.0 device controller capable of functioning as a Billboard class device.

>The USB 2.0 device controller can also support other device classes.

>

Q1) Does this mean that  i  can use CCG3 to support device classes such as UVC without using a device controller such as FX2LP? Is it stated that CCG3 can be used as a USB 2.0 device controller?

">The USB 2.0 device controller can also support other device classes."
Q2) So, I would like to know more about the above datasheet contents.

Best Regards

Hi everyone,

I use in my project SDK CYPD3120-40LQXI_dp_dongle.

During connecting Provider and Consumer, Consumer enable N-channel MOSFETs. I understand this is a dead battery mode.

I want disable Dead Battery mode.

Could you help me?

Best regards,

Nazar

CCG5 workspace incudes two projects:

1). backup_fw ( image-0)

2). CYPD5225 notebook ( image-1 )

How to change image-1 start address and meta data address ?

Hi cypress,

I'm using ccg3pa for my custom product.

CCG3PA will only be used as a PD, BC1.2 SNK device.

I'm facing problems if my code size crosses above 98.6% of FLASH.

Are there any ENUMS that i can disable for reducing the code size, As I already told, My product is used as PD,BC1.2 SNK only.

So I believe Source related Enums can be disabled to reduce code size.

Please suggest if any settings or Enums that i can disable to reduce my code size.

Regards,

Pranay.

Hi,

We are using the CYPD3177 EZ-PD as a DC barrel replacement, the application is marketed for.

Our target application requires a 20V, 90W supply (i.e. 20V & 4.5A or greater.)

We have configured the CYPD3177 using external resistors as follows:

20V supply, 4.5A or greater.

VBUS min = Rtop 0R, Rbot open = 20V minimum

VBUS max = Rtop 0R, Rbot open = 20V maximum.

Isink_Coarse = Rtop 5k1, Rbot = 10k = 4A.

Isink_Fine = Rtop 5k1, Rbot = 2k4 = 0.5A

1. Plug in a USB-C supply with the correct power rating, Fault line is low as expected, 20V is present to the application. Expected Behaviour.

2, Plug in a USB-C supply with underated current, Fault line is high, No voltage is presented to the application. Expected Behaviour.

3, Plug in a USB-A 5V supply with USB A-C cable, Fault line is low, 5V is presented to the application!

The datasheet clearly states:

"Pin 9 - FAULT - The EZ-PD BCR device pulls this line high if the power adapter cannot supply the required voltage or current "

I can almost understand if the chip was configured to allow 5V, then it might decide to let 5V though without negotiation.

But with 20V set as a minimum it should not let any power though without completing power negotiation.

Is this a know bug?

We have detected this behaviour during verifiaction and so need a resolution as soon as possible.

Please advise.

Mark.
